Also called bubbling.īLUSHING: A coating that becomes cloudy or dull through moisture or excessive solvent evaporation.īODY: The consistency of a coating. Soluble dyes or pigments in undercoat are dissolved by solvents in topcoat and stain through to the new finish.īLISTERING: The formation of bubbles or pimples on a painted surface caused by moisture in a topcoat before the previous coating one thoroughly dried or excessive heat. See Intermediate Coat.īINDER: The component of paint that joins pigment particles together to form the film and can determine many of the coating’s performance properties - washability, durability, adhesion, color retention, etc.īLEACHING: The process of lightening or restoring discolored or stained wood to its normal color.īLEEDING: Describes an undercoat staining through the topcoat. The non-destructive paint gauge uses measurement principle of magnetic induction for ferrous substrates and eddy-current for non-ferrous substrates.ABRASION RESISTANCE: A specially formulated coating property that protect structures against corrosion, damage and wear brought about by heat and moisture.ĪBRASIVE: Used for wearing away a surface by rubbing, scraping and sanding in preparation for coating examples include sandpaper and steel wool.ĪCRYLIC: A synthetic resin used in high-performance, water-based coatings.ĪDHESION: The ability of a coating to stick to a surface.ĪIR DRY: One method by which liquid coatings dry after solvent evaporation, the binders react with oxygen, or oxidize, creating a hard film.ĪIRLESS SPRAY: Applicator that pumps coating at a very high pressure through a hose with a tip designed to spray paint evenly in a fan-shaped pattern, covering more area quickly.ĪLKALI: A substance such as lye, soda or lime that can be highly caustic or corrosive to paint films.ĪLKYD: Any of a group of synthetic resins that are used in varnishes, paints and adhesives a paint in which the vehicle is an alkyd resin.ĪLLIGATORING: A paint failure that appears like small cracks resembling alligator skin due to too many coats, a topcoat applied before the basecoat fully dried or temperature changes that cause substrates to expand and contract.ĪNTI-CORROSIVE PAINT: Designed to inhibit abrasion and rust and applied directly to that’s used on iron, steel and other metallic substrates, often used as a primer for finish coats.īACK PRIMED: The application of paint to the backs of surfaces, such as exterior shingles, siding or trim to help prevent moisture from permeating.īARRIER COAT: A layer of a primer or coating that obstructs or prevents passage of water or other contaminants through a surface. ![]() Paint thickness gauges for dry film thickness can either be a non-destructive measurement or destructive measurement. Wet film gages can be used on virtually every substrate. They cover a wide wet film thickness range from industrial maintenance applications to thin coil coatings. A wet film thickness gage is an inexpensive, easy to use device. Wet film thickness should be monitored frequently to maintain an efficient coating process. Measuring the film thickness immediately after coating the surface is important to control the spreading rate and the final dry film thickness. Coating thickness measurement will monitor the paint process and maintain the appropriate coating properties. Applying too much coating can also be detrimental that can lead to excessive drying time, cracking, and flaking of the paint film. ![]() ![]() The proper film thickness has an impact on the paint opacity, appearance, and protective properties of the coating. Paint thickness is an essential parameter that needs to be measured routinely.
